I hear retired generals say Poo Poo and yet read the Pentagon is investigating plans. Really? or just "show".

It's a hard spot to be in.

He's the poo-poo-diaper-baby in chief so they have to do what he says.

Of course it is a waste of money and Trump only wants to have the parade because it will boost his ego, but I'm pretty sure that his response to criticisms will be to hit the "PATRIOTISM" button hard and long. For example, "What is wrong with these people who don't want to honor our troops? That's all this is for - to honor our troops. If you are against this parade, you are against our troops." A whole lot of people will buy it or it least be kowtowed into silence because of it.
